Introduction This document introduces a YANG [RFC6020] data model grouping for configuration scheduling. This grouping can be used in other YANG data models to specify a schedule applied on a configuration schema node, so that the schema node can take effect according to the schedule. 1.1. Terminology The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14, [RFC2119]. The following terms are defined in [RFC6020] and are not redefined here: o augment Liu, et al. Expires September 20, 2016 [Page 2] Internet-Draft draft-liu-netmod-yang-schedule-00 March 2016 o data model o data node 2. Configuration Scheduling YANG Data Model Overview This document defines a grouping "schedules" in the YANG module "ietf-schedule". Specifying this grouping for a YANG schema node allows to specify configuration schedules for the data objects modeled by this schema node. When such a schedule exists, system will configure the specified object according to the specified schedule. The grouping has the following structure: module: ietf-schedule grouping schedules: +--rw schedules +--rw schedule* [schedule-id] +--rw schedule-id uint32 +--rw start? yang:date-and-time +--rw schedule-duration? string +--rw repeat-interval? string 3.

Security Considerations The configuration, state, action and notification data defined in this document are designed to be accessed via the NETCONF protocol [RFC6241]. The data-model by itself does not create any security implications. The security considerations for the NETCONF protocol are applicable. The NETCONF protocol used for sending the data supports authentication and encryption. 5. References 5.1.
